Applio is the clearest free starting point for cloning a singing voice: it is a free voice-conversion suite with custom model training and real-time or uploaded-audio conversion. For a phone-first tryout, Humlo says it is free to try and turns a recording of your voice into a singing track. The other options below range from limited-credit web services to free, self-hosted projects; check each vendor’s current terms and whether its workflow suits your device before preparing a track.

Ranked Free AI Voice Cloners For Singing
1. Applio — Best Overall Free Voice Conversion
Applio is the strongest match when you want to train a voice model and convert an existing vocal, rather than generate a song from a text description. Its suite supports custom model training, model blending, uploaded audio, and real-time conversion. The vendor says it runs on Windows, macOS, Linux, and Colab, requires no account, and is MIT licensed. CLI automation and self-hosting options may suit technically confident creators better than someone seeking a one-click phone app.
A practical workflow is to prepare a clean recording of the consenting singer, train a model from that voice, then convert a separate vocal take and compare it against the original for pitch, timing, and intelligibility. Applio’s general conversion capabilities do not establish which input formats, hardware, or model settings will work best for your specific track; check the project documentation. Its site says Applio itself may be used, modified, and redistributed for commercial work, but that does not establish rights to a source voice, song, or trained model. Get the voice owner’s consent and check the project and source-material terms.

Humlo is the most direct option here for a singer who wants to try the idea from an iPhone. It says to record your voice once, choose a track, and create a singing performance in that voice; it can share or save the result as audio or a singing-head video. The stated device requirement is iPhone with iOS 16 or later. The free-to-try offer has no credit-card requirement, but the number of free creations and ongoing price are not stated.

For a first pass, record your own voice, select a track you have permission to use, and review the resulting vocal before sharing. Humlo lists multiple styles, including pop, R&B, rock, country, and K-pop, but that does not promise a particular result for every song. Check the app’s current terms for voice and track use, and get consent before using another person’s voice.
3. TopMediai AI Song Cover — Best For Custom-Model Cover Exports
TopMediai describes a free AI song cover generator that accepts uploaded MP3, WAV, or M4A files and YouTube links. It supports custom voice-model training from raw recordings and says a finished cover can be exported as a full mix, instrumental, or vocal track. Those separate exports can help if you want to review or arrange the converted vocal in another audio workflow.
Rank #2
- The FV01 vocal effects Corrector is primarily a pitch-correction pedal that offers everything from pitch correction to full-blown effects overload when your input is a microphone.
- The FV01 features three separate vocal effects as indicated by the TONE LED displayed prominently in the center of the pedal.
- Singers can switch between WARM, BRIGHT, and NORMAL modes, with each mode indicating the type of EQ manipulation provided by the pedal.
- It can be used as a microphone amplifier or a traditional stompbox. Optional 48V phantom power for condenser microphones.
- Two different output modes for a mixed-signal or individual signals from guitar and microphone.
The free label does not specify a credit allowance, file-duration limit, or which exports remain free, and the listed facts do not establish supported operating systems. Before uploading, confirm the current free limits and whether your chosen input source is allowed. Train only on a voice whose owner has agreed, and check TopMediai’s terms for the model, source song, and any intended sharing or commercial use.
4. Vocalize — Best Small Web Tryout
Vocalize is a browser-based cover and vocal toolkit. It says new signups receive three credits without entering a card, and users can choose from community-uploaded voices or clone their own voice. Inputs include audio, YouTube links, and text-to-speech; the vendor says a cover takes 10 to 60 seconds depending on song length. That timing describes processing, not a guaranteed turnaround for every upload. Its paid Converter plan is listed at $12.99 per month for unlimited generations and model uploads, while the directory notes there is no ongoing free plan and commercial use is restricted.
Rank #3
- From Subtle Pitch Correction to Hard Antares AutoTune Effect - VX5 is an intuitive vocal effects pedal with dedicated Retune Speed and Humanize knobs enabling adjustments with no computer needed
- The Classic AutoTune Sound - At the heart of VX5 is the iconic Antares algorithm, expanding the scope of effects available to vocalists; fit for live stage performance and studio sets alike

Use the trial credits on a short section of a track you are entitled to use, then listen for whether the converted vocal keeps the melody and words clear. The product facts do not establish a particular export format or supported singing genre, so check the site before building a longer session around it. Clone only with the voice owner’s consent; review Vocalize’s terms, especially its stated commercial-use restriction.
5. DDSP-SVC — Best Open-Source Singing Conversion Project For A Personal Computer
DDSP-SVC is specifically an open-source singing voice conversion project, making it a close technical fit for converting an existing sung performance. Its project description says training and synthesis have lower hardware requirements than SO-VITS-SVC and training can be much faster, while real-time conversion uses significantly fewer hardware resources than SO-VITS-SVC and probably slightly more than the latest RVC version. These are project comparisons, not a guarantee that a particular computer will run it smoothly.
Rank #4
- SIXTEEN VOICE EFFECTS AND THREE-PART HARMONIES – Offers 16 professional vocal effects and adds up to three-part harmonies to your voice in real time, giving singers, performers, and content creators a full vocal production toolkit.
- OPTIMIZES ANY MIC WITH BUILT-IN ENHANCER – Automatically optimizes any microphone's input signal with a built-in enhancer and supports condenser microphones with 48V phantom power for versatile mic compatibility.
- REVERB, DELAY, AND COMPRESSION AT YOUR FINGERTIPS – Fine-tune your vocal sound with dedicated compression, reverb, and delay controls for a polished, studio-quality tone whether performing live or recording at home.

- THREE AND A HALF HOURS ON 4 AA BATTERIES – Runs up to 3.5 hours on 4 AA batteries, making it easy to take your vocal processing anywhere for rehearsals, live performances, or on-the-go content creation.
The project lists a working combination of Python 3.11 on Windows, CUDA 13.0, PyTorch 2.9.1, and torchaudio 2.9.1. Treat that as a reported setup, not a universal installation recipe. Its maintainers explicitly ask users to train with legally obtained, authorized data and not use models or synthesized audio for illegal purposes. Get permission for a voice and check the project’s license and applicable source-track terms before distributing results.

RVC WebUI is a free, self-hosted toolkit for people prepared to install and configure a voice-conversion setup. The listed capabilities include training, model fusion, pitch controls, retrieval, batch processing, and real-time or offline conversion; it can export WAV, FLAC, MP3, and M4A. Hardware dependencies vary, and advanced model and installation controls make this a more technical choice than a web upload.
Best Value

A sensible first project is to train with an authorized recording, convert a short vocal passage, and adjust pitch or model settings while listening for artifacts. The project page is primarily in Chinese, so English-language setup support is not established here. Its repository states an MIT license; that covers the project license, not permission to imitate a singer or use a copyrighted song. Get voice consent and check the repository and source audio terms.
7. Uberduck — Best For Text-Driven Singing And Custom Voices
Uberduck supports speech, singing, and rapping from text, and says users can create custom voices for those outputs. It also advertises music generation from lyrics, support for more than 70 languages and hundreds of musical styles, and a free way to get started. The free allowance and whether custom voice creation is included in it are not stated, so verify those details before choosing it for a no-cost project.
For a text-led experiment, enter original lyrics and use a voice you own or have permission to use; for a converted existing vocal, confirm that Uberduck offers the specific input workflow you need, since that capability is not established in the facts here. The site says commercial use is available on any paid plan. Get consent for a cloned voice and check Uberduck’s terms for the voice, lyrics, and intended release.
How To Choose A Singing Voice Cloner For Your Setup
- Have a recorded vocal to transform: Start with a conversion workflow such as Applio, DDSP-SVC, or RVC WebUI. The latter two require a local setup; Applio also has self-hosted options and a Colab route listed by its vendor.
- Want to record on a phone: Humlo’s stated iPhone workflow is the most directly specified mobile option in this roundup.
- Want a web cover workflow: Vocalize and TopMediai describe browser-based cover or upload workflows. Check current limits and input requirements before preparing a full-length song.
- Want lyrics turned into singing: Uberduck explicitly supports singing generation from text. Applio and the local conversion projects are voice-conversion tools, so plan on supplying sung audio rather than assuming they compose a melody from a prompt.
- Need a particular genre, language, file format, or device: Use only the specifics established above as a starting point. If the tool’s entry does not state your requirement, check the vendor or project page before committing to it.
Consent And Release Checks
A voice model can make a performance sound like its source singer. Use your own voice or get the person’s clear permission before training or generating with their voice, and check each platform’s terms for voice models, source tracks, and sharing. Spotify said in September 2025 that vocal impersonation is allowed on its service only when the impersonated artist has authorized it; it also announced an AI Persona badge in August 2026 for artist identities that may be AI-generated rather than a real person. Those are Spotify policies, not universal platform rules. Read the report on Spotify’s 2025 AI protections and Spotify’s 2026 AI Persona announcement.
